MlDDLlNGS-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 348,754, dated September 7, 1886.

Application filed January 25), 1886. Serial No. 190,186. (No model.)

To (tZZ whom it may concern:

Be it known that l, \VILLLUI H. LIKINS, of Jackson, in the county of Jackson and State of Michigan, havinginvented new and useful Improvcments in Middhugs-Purifiers; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in middlirigs-purifiers; and the invention consists in the novel combinations audthc peculiar construction and arrangement of parts, all as more fully hereinafter described, and specifically set forth in the claims.

In the drawings which accompany this specification, Figure 1 is a front elevation of my improved purifier. Fig. 2isa vertical central cross-section on the line a: 00 in Fig. 1. Fig. 3 is a horizontal section on the line 3 in Fig. 1. Fig. l. is an enlarged section of one of the middlings-purifiers proper.

A revolving reel, A, inclosed in a proper case, B, is supported by a suitable frame and forms the upper portion of the machine. This reel may be of any of the known descriptions used for bolting, and is covered with cloth of different grades of fineness.

O are cant-boards which direct the middlings bolted through the reel to the conveyer. 1) and E are spouts into which the conveyer carries the middlings. The conveyer is preferably so arranged that each grade of middlings is carried to one of the spouts only and conducted by it to the purifiers proper, of which there is one to every spout. These purifiers are all of like construction, and are arranged as follows: Each. of the spouts E extends downward and connects at itslower end with a cylindrical chamber, F, of which the discharge end ofthe spout forms the eye. Goncentrically within this chamber and near the top thereof, so as to form passages N O, is placed the horizontal revolving disk G, which is secured on a vertical shaft, H. The shaft H is held in suitable bearings, and is provided with a pulley, I, by means of which motion is transmitted to this shaft from the main shaft .T. Below the revolving spreader-disk G- is secured the stationary cylindrical wall K, pro- Vided at its lower end with an outwardlydefleeting flange, L, all so arranged as to form between said deflector and the cylindrical wall of the chamber F an annular passage,M,which connects with the passages N O and forms a vertical downward continuation thereof, terminating in an outward annular dischargeopening, 1?, below the cylindrical wall of the chamber F.

R is a cylindrical case concentrically inclosing the above-described parts. It is provided at its lower end with an inwardly-inclined flange, S, and at its upper end with a conical hood, T, all so arranged as to form an outer annular air-passage, U, which at its upper end connects with the trunk-flue V. The lower end of this passage extends beyond the annular opening Pandlcommunicates with the outer air through the annular opening Y, left between 7c the flange S, aud'the hopper Z, secured below it. The hopper Z has a discharge-opening into the conveyer a, which latter is placed under neath and connects with all the other purifiers in a similar manner. The trunk-fines V are all connected with the flue b, and suitable valves, (1, are placed in these connections. The flue b, which leads to a suction-fan, c, is also provided, preferably, with one or more separator-trunks, e, which at their lower ends have discharge-openings provided with hinged val ves f into another conveyer, g. The power is preferably conveyed to the main shaft I, supported in suitable bearings on the front side of the machine, and from there it is transmitted by suitable belts or chains to the other operating parts.

The operation of this machine is as follows: The middlings are fed to the bolting-reel A, which is constructed and arranged to operate 0 in the usual manner. The material passing through the cloth into the conveyer-trough undcrneathis carried, each grade separately, into the spouts E, which conduct the material to the purifiers proper. These purifiers all 5 operate in like manner, and each one for itself performs a complete operation. The material falls through the spout E on top of the revolving disk G and near the center thereof, and by centrifugal force, which is quickly im- IOO parted to it by the'high speed with which said disk revolves, it is thrown outwardly, and at the same time is spread in a thin and even sheet. In this form it falls into the annular passage M, and is then deflected outwardly by the flange L through the opening 1. Being still farther spread thereby, and at the same time having lost its momentum, it is struck by a current of air produced by the suction. This current of air passes in through the annular opening Y, and takes its course upwardly toward the passage U, where it strikes the ma terial, spouting out through the opening P at a right angle, or nearly so, enabling it to load itself with all the impurities and carry them away in an upward direction, while the purified middlings fall to the bottom and are directed by the flange S into the hopper Z, which discharges them into the conveyer a. The material in dropping from the flange S into the hopper is thus traversed a second time by an air-current. The impurities carried off by the air-current are conducted upward through the passage U into the trunk V, from which they are drawn through the air-flue 1) into the suction-fan and discharged from there.

By means of the valves d the air-currents passing through each purifier can be regulated to act in the best manner, and should any good material be carried up into the suction-flue bit will there drop out of the aircurrent into the separator-trunks e, which, for this purpose, are suitably arranged to collect such material and discharge it into a separate conveyer, g, from which it is disposed of in any desired manner for further reduction.

It will be seen that as many of the purifiers proper as desired may be combined in a single machine, and the purified product of each may be singly collected and delivered to to the proper rolls for further reduction.

It is evident that the construction of the machine described may be variously modified within the spirit of my invention.

My improved machine is able to accomplish a much larger amount of work compared with other machines of equal size in present use, and as floor-space is a great desideraturn in mills the advantage gained thereby is obvious.

Vhat I claim as my invention isp 1. In a middlings-purifier, the combination of the feed-spout E, conveyer D at the entrance of said spont, the cylindrical case It, the rotary disk G, arranged to spread the material by centrifugal force, the cylindrical partition F, forming annular passages M U, said passage M arranged Ito receive and carry the material, the lateral discharge-spout P, and means for producing an upward air-enrrent through passage U, all arranged and operating substantially as described.
